The opposite arm is loadedwith a weight to counterbalance the wooden frame, and to enable the workman to ascer-tain the proper size of the candles. The end of the lever which supports the frame isplaced immediately above the dipping-cistern; and the whole machine is so balanced that,by a gentle pressure of the hand, the wicks are let down into the melted tallow as oftenas may be required. The following convenient apparatus for dipping candles has been long in use at Edin-burgh. In the centre of the dipping-room a strong upright post a a, jig. 253, is erected,with turning ii-on pivots at its two ends. Near its middle, six mortises are cut at smalldistances from one another, into each of which is inserted a long bar of wood b b, whichmoves vertically upon an iron pin, also passing through the middle of the shaft. Thewhole presents the appearance of a large horizontal wheel with twelve arms. A complete CANDLE. 253. view of two of them only is given in the figure. From the extremity of each arm issuspended a frame, or port, as the workmen call it, containing 6 rods, on each of which are hung 18 wicks, making the wholenumber of wicks upon the wheel machine, though apparently heavy,turns round by the smallest effortof the workman; and each port, asit comes in succession over the dip-ping-mould, is gently pressed down-wards, by which means the wicks areregularly immersed in melted the arms of the lever are all of thesame length, and as each is loadedwith nearly the same weight, it isobvious that they will all naturallyassume a horizontal position. In or-der, however, to prevent any oscil-lation of the machine in turninground, the levers are kept in a hori-zontal position by means of smallchains a a, one end of which is fixedto the top of the upright shaft, andthe other
